Audited Supplier HDPE is a highly crystalline, non-polar thermoplastic resin. High-density polyethylene is a white powder granular product, non-toxic and odorless, with a density in the range of 0.940~0.976 g/cm3; crystallinity is 80%~90%, softening point is 125~135ºC, and the use temperature can reach 100 ºC; The melting temperature is 120~160ºC. For materials with larger molecules, the recommended melting temperature range is 200~250ºC. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength.
